Hello Robert. I know that this topic is a little old. But I'm Still having that problem with LineStipple....
I've been debugging Osg src with my implementation. And I've realized that when I'm adding the Line inside my PAT object I just can't see it calling Drawable::compileGLObjects( State &state ) ( OSG 1.x ).... Is there any way that I could do it by hand ? 2008/6/26 Robert Osfield <[EMAIL PROTECTED]> > Hi Andre, > > If your lines are coming out stippled then it suggests that either > your own OpenGL code is setting the line stippling on, or that the OSG > has a osg::LineStipple assigned to enable this. > > Robert. > > On Wed, Jun 25, 2008 at 3:02 PM, Andre Simoes <[EMAIL PROTECTED]> > wrote: > > Hi For all. > > > > Does anyone had such problem ? > > > > I'm using a system that merges calls between pure openscenegraph updates > and > > opengl updates.
